Interestingly, stronger communication, which was related to chemo‐attraction (CCL2‐CCR2, CCL2‐ACKR1, CCL11‐ACKR1) and angiogenesis promotion (VEGF‐VEGFR), from pericytes to endothelial cells and tumour cells was identified in the solid components than in the GG components (Figure 5L). This evidence concerns the gene CCL11 and neoplasm.
